- The Buff-breasted Sandpiper is unique among North American shorebirds in having a lek mating system. Males defend relatively small territories that provide no resources for females and are simply display sites to which females can be attracted. Females select a mate and then leave to nest and raise their chicks elsewhere.
Breeds in dry, grassy tundra. On migration and in winter found in dry grasslands (usually short grass), pastures, plowed fields and, rarely, mudflats.
- Clutch Size
- 2–5 eggs
- Condition at Hatching
- Active and covered with down.
Buff-breasted Sandpiper populations once numbered in the hundreds of thousands to millions, but by the 1920s hunting had brought this species close to extinction. Once regulations were put in place, numbers increased, but they appear to be declining again. Because these birds do not always return to the same breeding and wintering sites, numbers are difficult to monitor, but data from migration sites in North American migration sites estimate the current population at 16,000-84,000 individuals. This species is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action.
